I used to play with no compression and would control the booms with my fingers, I quite liked it. But more recently I've found that when playing live, we're a little bit louder and I needed some help. The amp has its built-in compressor and I experimented a bit and got a sound I liked with the knob at noon (lucky me). Trouble is, even with the Gain @ 2 O'clock (I used to have it at 10 O'clock), I don't get the dirty sound of the little Peak light flickering. So, when I play the rockers, which knob would be best to turn? Compression down/Gain up/Volume something/A mixture of all three? I don't mind turning the odd knob, but if it gets too strenuous, I'd rather save my time. I'll get a pedal of some sort if it's unavoidable, but it's a last resort for me. I already own a BOSSME-50B and a Tech21 Bass Boost Fuzz, if they'll help, but I haven't dared gig with them yet. You have to understand that I live in North Queensland where double-pluggers are considered an extravagance worn only by show-offs; and where turning up with all your strings is "a bit flash", let alone matching socks. Bass is a NT StingRay HH (all the knobs at noon and mostly played in posn 3, but back to 1 for the rockers). Cabs are PF112 & PF410. Lots of places this thread could go. I picked here seeing as I'm really after some amp settings recommendations.
